Analysis of junior high school students' science process skills through the implementation of PHET simulation media on the subject of light and optics

Abstract

The purpose of this study was to determine students' science process skills in the subject matter of Light and Optics  learning process with  PhET simulation media.  The parameters of four (4) aspects of basic science process skills indicators, namely observation, measurement, prediction and conclusions.. This research is a quasy experiment using quantitative descriptive analysis. The research subjects were 32 students of State Junior High School 4 Palangkaraya. The assessment instrument used is a science process skills assessment sheet with skill scores in the form of a Likert scale. The results of the science process skills assessment per component at each meeting showed several results.  Quite good results in the observation and prediction components, good results in the measurement component, and very good results in the conclusion component.  The results of the science process skills assessment per aspect at each meeting showed quite good results in the aspect of accuracy in making hypotheses, accuracy in answering questions related to observation results. Good results in the aspects of accuracy in conducting experiments in accordance with work procedures, accuracy in processing data, and accuracy in proving hypotheses. Very good results in the aspect of summarizing experimental results. The highest aspect value is concluding the experimental results at 89.58% in the very good category.  The average results of the science process skills assessment per group at all meetings were obtained as quite good and good. Group I scored 68.06% (quite good), group II scored 70.83% (good), group III got 66.67% (quite good), and group IV got the highest score, namely 72.22. % (Good).
